The road on the steep section about 1 in 7. Some surplus brown gravel was applied by a frontager but was soon washed out. Some other surplus DGM was brought in from a neighbouring road but also soon washed out leaving the road as shown in the picture on the left with the white marks.
A few years previously the Council supplied surplus planings and these were laid the length of the road and compacted. The road was much improved for 3 to 5 years but eventually storm water washed it out.
By 2017 residents of which there are 18 frontagers to Zig Zag Road and 11 residents in the spur road Leacroft Road felt that this constant tinkering was not the solution. The loose surface was dangerous to use for walkers and eventually the ridges on the steep section made it nearly impassable to cars and the normal refuse lorry stop using the road. Re-Drive were contracted and now we are enjoying the benefits of a road both safe to walk on, well draining and pleasant to drive on.
Water erosion down the middle of the road
An example of the sub strata of the road. The picture on the far left shows some of the surplus basalt chips given to us in 2012 by a neighbouring road which are now embedded in the road.
The extra planings needed to raise the level
A 3 foot deep French drain filled with 20mm shingle
The bend leading to Welcomes Road
The steep section after the cement and water incorporated being compacted
Below this man hole cover is a 20ft deep hole down to the sewer dry lined with brick. Surface water is not sent down through this cover which anyway soon blocks up with debris washed down from higher in the road
After the storm in the night
The dog had to go for its walk!!! Not very helpful.
The cement stabilisation system requires the use of 200 hp tractors.
The cement stabilisation process was messy. This was the first urban job carried out by Re-Drive and since then they have improved the way surrounding areas are protected from cement spray. Frontagers can also cover their own drives. The link below describes the cement stabilisation process which as far as possible uses the material already in the roadway. In the case of Zig Zag Road the level of the end leading to Abbotts Lane needed raising and planings were brought in. The current appearance of the road leaves something to be desired but there is no doubt about its load carrying capacity and the smooth surface has reduce tyre noise to virtually zero. In winter the road seems no more or less slippery than other roads in the vicinity.
If you are reading this and want your road rehabilitated please mention this web site to Re-Drive.
Work parties in 2020 and 2021. The road still holding up in spite of some very heavy HGVs plying it from time to time on way to Welcomes Road and back.
